Show basic metadata fields for generic work (#6321)

* Add yaml file designation

gets around `Psych::SyntaxError:                                                                                                                                                                      (<unknown>): control characters are not allowed at line 1 column 1`

which was happening during schema load when running
spec/features/work_show_spec.rb

* Add a work show feature spec that runs in koppie

* Show basic metadata fields for generic work

closes #6276
